2. SCHOOL PLAN Speed Security Growth
Design a school network that will allow all connected
workstations the ability to connect at a minimum of 1 Mbps.
Security
Design the network in such a manner that there is reliable
security separating the curriculum & administrative systems.
Growth
Design the school network at a minimum of cost to the school
but one that allows for future technologies to be added easily.

21. Specific IP addresses Teacher Workstations: 10.6.0.10-250
Teacher workstations, Servers, and Printers will be Static IP addresses.
Teacher Workstations:
Network Printers:
Students will obtain an IP address from the DHCP server.
Numbers will be in the range of
x to x

22. Access List Logic
Basic Premise; all workstations on 10.5.x.x and workstations on 10.6.x.x have access to devices located on the 10.7.x.x subnetwork. However, ONLY port 80 will be allowed OUT of any device located on the 10.7.x.x subnetwork.
F.M. Internet 80

23. Access List
In order for the curriculum and administrative portions of the network to remain segmented, an access list will be placed on the school router.
The only data that can travel from the student computers to any other part of the network is HTTP.
Access-list 105 permit IP
Access-list 105 deny IP
Access-list 105 permit TCP any eq 80
Interface fx1
IP Access-group 105 in

24. VLAN
In order to keep the students limited to only their specified address range, the need for a Virtual LAN has been created.
The goal is to limit student activity on administrative
locations, but still allow administrators to use student
services. {I.E. Printers or Library Server}
On every switch in the IDF’s, we will specify which ports are for VLAN1 (Administrative) and which ports are for VLAN2 (Curriculum).

25. Servers NAME IPX Name IP Address
Administrative Server: DV_Admin
Curriculum Server: DV_App
Library Server: DV_Lib
Network Server: DV_Net
Note:
The Network Server will be running the Cisco Server Suite 1000,
allowing DHCP for student machines, storage, and other WAN activities.

26. SPEED With the system that we have designed, the
Design a school network that will allow all connected
workstations the ability to connect at a minimum of 1 Mbps. However, the TCS also requires that the LAN will grow at 1000% over the next 5 years. This breaks down to a minimum of 10 Mbps per workstation.
With the system that we have designed, the
network will perform at 100 Mbps to every
teacher workstation and 90% of all
student workstations.

27. Security Design the network in such a manner that there is reliable
security separating the curriculum & administrative systems.
With our network design, students can perform all their activities in their network. However, they cannot access information on the Administration server because of the VLAN. They cannot access information located at the Central office because of the restrictions in the Router’s Access List. They can reach the Internet through the Network Server’s DHCP’s functions and the permissions set in the Router’s Access List.

28. Growth Due to the fact that we are responsible for the performance of
our network, we wanted to create the best possible performing
network. With the layout of the IDF’s and classroom
cabinets, upgrading the entire network could be modified
by simply changing the Network components. However,
by creating a switched network NOW, the need to upgrade the
network has been postponed as this design will perform
the tasks necessary for many years. We were also required to
supply 24 student workstation ports. We have designed for a
possible 30 workstation in each room.
Design the school network at a minimum of cost to the school
but one that allows for future technologies to be added easily.
